The gamecard in nintendo?

Jan. 4, 2013

My Brother’s game card (Black 2) is not working in my nintendo 3ds. It used to be when I put it in and selected it the screen would say"Could not access save data. Please turn off power and try again"

Now when I put it in the icon doesn’t even show up.All of my other game cards work perfectly fine.Has anyone had this problem before and if so were you able to fix it?

p.s. I wasn’t sure where to ask this. You can comment if I should ask this somewhere else and I will fix that.

Ok this is because you have used it in two different DS’s. If you use Wifi on one DS then use wifi on the other it screws up the Gamecard. You can only use wifi on Pokemon on one DS. So just use the Black 2 on your brothers DS and don’t make the same mistake again.

Hope this helps ^.^

EDIT: If you have got far in your game unlucky because I have been researching and the only way to stop this is to reset the whole game. Sorry to be the messenger of bad news. :(
